Remington 740 / 760 Rifles

Bob Dunlap
understands the design, function, and repair of these extremely popular deer
woods guns as well as anyone. These semi-auto and pump action guns are, with
the exception of the force causing the action bars to move (hot gas or your
hand), are practically identical. In fact, the trigger groups (as well as those
on their 870 and 1100 shotguns) are identical. This course covers all of the
models and variations of this series of rifles.

Using a
cut-a way gun and the important variants, Bob shows you everything you need to
know about getting them apart and back together again and understanding the
changes along the way and why they were made. The weaknesses of the versions,
and their strengths, are shown and explained as only the master can. If you want
the quick course on how to maintain these guns, and operating as intended, then
this course is for you (if you want the long course, look into our basic 108 hour
Professional Gunsmith Course.)

If you
noticed how often the terms "explanation" and "visual
